the 16 Black Velvet on the Lincoln vehicles is just black, no metallic or silica flakes at all. I expect the Ford black is identical but have not personally confirmed this.
for 17, there is a new black that is black metallic but not like Tuxedo Black which had the silica flakes. the new black is "regular" black metallic paint. as I understand it, the silica flakes came from a place in Japan that was affected by the tsunami a few years back, and the supply has gotten unpredictable. who knows if that is true or just an urban legend...
